Description

Decorative substrate and touch panel thereof

The present invention relates to a decorative substrate and a panel thereof, and more particularly to a decorative substrate having a light transmissive pattern region and a touch panel thereof.

With the rapid development of the optoelectronic industry, users require electronic devices (such as display panels, touch panels, touch display panels, etc.) to have high response speed, high sensitivity, low power consumption and other performance characteristics, and also expect electronic devices to have Other tips or decorative functions, such as displaying a logo, a pattern, a text, an operation menu, or a status prompt by means of a light-transmissive display pattern. For example, the light-transmitting display pattern used as the state prompt can be combined with a sensor or the like to generate different display effects in different situations, such as changing the color of the light source, the illumination range of the light source, or flickering.

In the case of a touch display device, the touch panel is stacked on the display module to provide direct interaction between the user and the display screen. In order to transmit the signal generated by the user operating the touch panel, the plurality of sensing elements of the touch panel transmit signals to the control circuit or receive signals from the control circuit via a plurality of signal wires. Usually, the signal conductor requires a lower impedance to facilitate the transmission of the signal, so the signal conductor is mainly visible gold. It is composed of materials. In order to prevent the components of the signal wires or other touch panels from being exposed to the outside and affecting the appearance of the overall device, the periphery of the touch panel is often provided with a decorative layer to shield the visible wires or other components to be shielded. In this way, when the light-transmitting display pattern is applied to the touch display device, the prior art forms a perforation in the decorative layer at the position corresponding to the backlight, but the design will cause the user to see the rear backlight through the through hole, causing the touch. The appearance of the control display device is degraded.

The existing improvement method mainly solves the problem of backlight visibility by further providing a coating having a low light transmittance in the perforation or by reducing the size of the perforation. However, the existing design does not allow the light beam to change through the perforated beam, and even if the light intensity of the light source is changed, the user can only see the light source reacting brightly, not brightly or flashing. Therefore, how to make the light-transmitting display pattern have a better display effect is still a problem that the relevant industrial personnel desire to improve.

The invention provides a decorative substrate and a touch panel using the decorative substrate. The light transmissive pattern area of the decorative substrate can generate a change of light shape after the light beam penetrates the decorative substrate, thereby providing more light transmittance for display effects. Display the pattern.

In other embodiments, a plurality of electrode patterns may be respectively connected to the respective signal wires and distributed in a button type (for example, US Pat. No. 4,954, 823), that is, each electrode pattern is used as a sensing unit, and the target is detected according to the self-capacitance measurement method. The coordinates or movement of objects (such as fingers).

Furthermore, the material of the electrode patterns 120 and 120A is not limited in the present invention. For example, the material of the electrode patterns 120 and 120A may be a transparent conductive material such as a metal oxide, a carbon nanotube, a nano silver wire, a graphene or a terpene. Place The metal oxide is, for example, indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, indium antimony zinc oxide, or other suitable oxide, or a composite laminate of at least two of the foregoing.

To improve light transmission and reduce visibility. Among them, the non-metal substrate is, for example, a polymer glue.

The decorative area A1 includes a shielding area A11 and a light-transmitting pattern area A3. The shielding area A11 is located on at least one side of the light-transmitting pattern area A3, and the area of the shielding area A11 is larger than the area of the light-transmitting pattern area A3. The masking area A11 can be configured corresponding to an element that is not to be displayed but needs to be shielded. The component that is not to be used for display but is to be shielded is, for example, a visible signal conductor 130. The light transmissive pattern area A3 can be configured to correspond to a light source LS. The light source LS can be an independent light source, such as a light emitting diode source. Alternatively, when the touch panel 100 is integrated with the display module (not shown) to form the touch display panel, the backlight of the display module or the self-luminous light source of the display module can also be used as the light source of the touch panel 100. LS. The light source LS is disposed behind the decorative substrate 110 to provide a light source required for the light-transmitting pattern area A3. The rear refers to the side of the decorative substrate 110 that is relatively far from the user when the touch sensing is performed.

In this embodiment, the first decorative layer 114a is disposed on the periphery of the substrate 112, wherein the first decorative layer 114a covers the shielding area A11 and forms a light transmissive display pattern in the transparent pattern area A3. The light transmissive pattern area A3 has at least one first light transmissive area A31 and at least one second light transmissive area A32, and the second light transmissive area A32 is located on at least one side of the first light transmissive area A31. In this embodiment, the second light transmitting area A32 is, for example, a surrounding device. It is placed around the first light transmitting area A31. The light transmissive display pattern has at least one first light transmissive pattern W1 and a plurality of second light transmissive patterns W2 respectively corresponding to the first light transmissive area A31 and the second light transmissive area A32. The area of the first light transmissive pattern W1 is larger than the area of each of the second light transmissive patterns W2. The light shielding pattern 116 is disposed in the first light transmission pattern W1, wherein at least two light shielding patterns 116 are spaced apart, and at least two second light transmission patterns W2 are spaced apart. For example, the first light transmissive pattern W1 and the second light transmissive pattern W2 may be formed by forming an opening penetrating the first decorative layer 114a, but the invention is not limited thereto. In another embodiment, the first transparent layer W1 and the plurality of second transparent patterns W2 may also be formed by thinning the first decorative layer 114a to a degree of light transmissibility. That is, the thickness of the first decorative layer 114a in the shielding area A11 is greater than the thickness of the first decorative layer 114a forming the first light transmitting pattern W1. In addition, a light transmissive material such as ceria or a transparent organic material may be filled in the opening of the first decorative layer 114a, but the invention is not limited thereto.

In this embodiment, the light-shielding pattern 116 and the first decorative layer 114a are made of the same material, and both can be formed simultaneously by printing, or the light-shielding pattern 116 can be formed by patterning a light-shielding material layer at a time, and the first light-transmitting pattern is formed. W1, the second light transmissive pattern W2 and the first decorative layer 114a corresponding to the shielding area A11. The patterning method can be yellow light or laser etching.

By providing the light shielding pattern 116 in the first light transmitting area A31, the amount of light passing through the first light transmitting area A31 can be adjusted. Further, when the total area of the light shielding patterns 116 is divided by the area of the first light transmission pattern A31 by more than 80%, when the light source LS is turned off and the touch panel 100 is 30 cm away from the user, the first light transmission area A31 versus The shaded area A11 will be hidden due to its similar appearance. That is to say, the human eye cannot clearly distinguish the difference between the first light-transmitting area A31 and the shadow area A11.

As shown in FIG. 1C and FIG. 1D, the second light-transmissive pattern W2 of the present embodiment is disposed around the first light-transmissive region A31, for example, and the first light-transmitting pattern W1 and the second light-transmitting pattern W2 are surrounded by the same. The central axis. Further, the second light transmitting area A32 has the same shape and different size as the first light transmitting area A31. Thereby, when the light beam emitted by the light source LS passes through the light transmitting pattern area A3, the light type of the light beam passing through the first light transmitting area A31 is different from the light type of the light beam passing through the second light transmitting area A32, thereby allowing the light to pass through The light pattern of the light beam of the pattern area A3 can have more variations.

Specifically, the second light transmissive pattern W2 and the light blocking pattern 116 can be used to modulate the light transmittance of the light transmissive pattern area A3. In this embodiment, the shape of the light shielding pattern 116 and the second light transmission pattern W2 is, for example, a circle, and the diameter R116 of each of the light shielding patterns 116 and the diameter RW of each of the second light transmission patterns W2 are less than 50 μm, respectively, and adjacent The center distance D116 of the light shielding pattern 116 and the center distance DW of the adjacent second light transmission pattern W2 are each less than 100 μm. In another embodiment, when the touch panel 100 is applied to the handheld electronic device, the diameter R116 of each of the light shielding patterns 116 and the diameter RW of each of the second light transmission patterns W2 may be less than 20 μm, respectively, and the adjacent light shielding patterns 116 The center distance D116 and the center distance DW of the adjacent second light transmission pattern W2 may be less than 40 μm, respectively. Thereby, the visibility of the light-shielding pattern 116 and the second light-transmitting pattern W2 to the human eye is further reduced, so that when the light source LS is turned off, the light-transmitting pattern area A3 and the masking area A11 are concealed due to the similar appearance. That is, the human eye cannot clearly recognize the boundary between the light-transmitting pattern area A3 and the masking area A11. It should be noted that this Although the shape of the light shielding pattern 116 and the second light transmission pattern W2 is circular, the present invention is not limited thereto. In other embodiments, the shape of the light shielding pattern 116 and the second light transmission pattern W2 may also be a polygon, a straight line, a curved line, a meander line, or a combination thereof.

Through the shape, size, density, and arrangement design of the light shielding pattern 116 and the second light transmission pattern W2, the light source emitted by the light source LS can generate different light shape effects after passing through the light transmission pattern area A3. Further, different light shape changes may also be generated depending on the light intensity variation of the light source. For example, the size of the light shielding pattern 116 of the present embodiment increases as the distance between the light shielding pattern 116 and the contour of the first light transmission pattern W1 decreases, and the size of the second light transmission pattern W2 follows the second transparent pattern. The distance between W2 and the first light-transmitting pattern W1 is increased by decreasing. Thereby, the light transmittance of the light-transmitting pattern area A3 of the present embodiment is outwardly decreased from the central axis, and the periphery of the first light-transmitting area A31 can have light composed of the light beam passing through the second light-transmitting pattern W2. Halo, while providing a special light type. Further, when the light intensity of the light source LS is relatively low, a display pattern having a relatively small light pattern can be obtained, and when the light intensity of the light source LS is relatively high, a display pattern in which the light type is relatively large and the halation effect is relatively remarkable can be obtained. In other words, compared with the prior art, the design of the light-shielding pattern 116 and the second light-transmissive pattern W2 in the light-transmitting pattern area A3 can improve the diversity of light-type changes.

Of course, the embodiment of the light-transmitting pattern area A3 of the present invention is not limited to the type of FIG. 1C. As shown in FIG. 3, the second light transmissive patterns W2 may also be located on the same side of the first light transmissive pattern W1 and adjacent to the first light transmissive pattern W1. Further, the shape of the first light transmitting region A31 may be different from the shape of the second light transmitting region A32.

Wherein, along the drag direction of the second light transmissive pattern W2, the size of the light shielding pattern 116 has an increased variation, and the size of the second light transmissive pattern W2 has a reduced variation. Thereby, in this embodiment, the light transmittance of the light-transmitting pattern area A3 is decreased from the star to the tail, and the main pattern formed by the first light-transmitting pattern A31 has the halo extending. Moreover, as the light intensity of the light source LS (shown in FIG. 1D) changes, the light-transmitting pattern area A3 can also obtain different light-shaped effects, for example, having different sizes of halos.

In addition, as shown in FIG. 4, the number of the second light-transmitting regions A32 may be plural, and the second light-transmitting region A32 is located, for example, on the same side of the first light-transmitting region A31, and the second light-transmitting region A32 is The first light transmissive areas A31 are at least 0.04 mm apart so that the outline of the different light transmissive areas can be clearly recognized by the human eye. Further, the shape of the first light transmitting region A31 may be different from the shape of each of the second light transmitting regions A32. In this embodiment, the shape of the first light-transmitting area A31 is, for example, the shape of the English letter "P", and the shapes of the second light-transmissive areas A32 are respectively the English letters "a", "t", "e", The shape of "n", "t". The size of the light shielding pattern 116 located in the first light transmitting area A31 is increased as the distance between the light shielding pattern 116 and the second light transmitting area A32 is decreased, and the size of the second light transmitting pattern W2 is increased by the second The distance between the light pattern W2 and the first light-transmitting area A31 is decreased. In this embodiment, the light transmittance of the light-transmitting pattern area A3 is decreased from the letter P to the letter t. Moreover, as the light intensity of the light source LS (shown in FIG. 1D) changes, the light-transmitting pattern area A3 can also obtain different light-shaped effects.

Further, after the substrate 112 is bonded to the cap plate 112a, the first decorative layer 114a, the second decorative layer 114b, and the semi-transmissive layer 150a are located between the substrate 112 and the cap plate 112a. It should be noted that this embodiment is not intended to limit the implementation of the first decorative layer 114a and the second decorative layer 114b. In an embodiment not shown, the first decorative layer 114a may form only the light shielding pattern 116, and the second decorative layer 114b forms the first light transmitting pattern W1 and the second light transmitting pattern W2, and the semi-transmissive layer 150 Covering the area of the cover plate 112a corresponding to the light-transmitting pattern area A3 and the second decorative layer 114b located in the light-transmitting pattern area A3.
